What to do about greasing a Honda rancher with no fittings?

We have too honda ranchers .We run them throw mudd and creeks and dirt and sand and this fall we brought them home for me to service and I went to grease them and their is NO grease fitings!! why wouldnt they put grease fiting on them?|||hondas dont use grease fittings ,their suspension parts are made so regular greasing isnt needed as are most cars now ...you can buy a needle that snaps into a grease coupling that you can pierce the boot of the part and add grease|||It is what is called a closed in system. Which means it comes with no grease fittings.
